Homework Statement
A particle of mass m is thrown vertically upwards with initial speed v. When the particle returns to it starting point, what are the changes in momentum and kinetic energy of the particle.
Homework Equations
P=mv KE=1/2mv2
The Attempt at a Solution
The answer to this question is change in momentum = 2mv while there's no change in KE, but I really don't understand how to calculate them?
